[Detailed description of the invention] Industrial application field This invention relates to an identification structure for a compatible cartridge case, and in particular, for example, for a recording/reproducing device to identify a dedicated cartridge case containing an information recording disk as a compatible cartridge case. This invention relates to an identification structure of a compatible cartridge case useful for.

Prior art and its problems In general, disc-shaped recording media (hereinafter referred to as disk discs) are not compatible with recording and reproducing devices based on other different methods due to differences in their recording and reproducing methods. There is. Moreover, since there are many different shapes of cartridge cases that house disk disks and mechanisms for driving these disk disks, it is not easy to identify compatibility, and it is not easy to identify cartridge cases that are not compatible. If the cartridge is loaded into a recording/reproducing apparatus, there is a risk that the cartridge case itself or the internal structure of the recording/reproducing apparatus may be damaged.

However, conventionally, no countermeasures against such problems have been proposed.

Purpose of the invention Therefore, the main purpose of this invention is to identify the compatibility of the cartridge case with the recording/playback device, prevent damage to the main body of the recording/playback device and the cartridge case, and reduce the number of malfunctions of each. It is an object of the present invention to provide an identification structure for a compatible cartridge case.

Structure of the invention In order to achieve the above object, the main means adopted by this invention is a cartridge case that is removably loaded into a cartridge case loading section of a recording/reproducing device, and at least one of the cartridge cases is first and second engaging step portions are formed on one side, and the cartridge case loading portion is configured to abut on the first engaging step portion when the cartridge case is loaded into the cartridge loading portion. a contact member; and a sensor piece that can be engaged with the second engagement step while the contact member is in contact with the first engagement step, the sensor piece being attached to the second engagement step. When the cartridge case is engaged, a signal for confirming the position of the cartridge case is sent from a sensor connected to the sensor piece.

Function When a predetermined cartridge case is loaded into the cartridge case loading section, the abutting member of the cartridge case loading section comes into contact with the first locking step formed on the cartridge case.

In response to this, the sensor piece installed in the cartridge case loading section engages with the second locking step part of the cartridge case, and the sensor connected to this sensor piece is connected to the loaded cartridge case. Sends a position confirmation signal.

On the other hand, the distance between the contact member of the cartridge case loading section and the sensor piece is set as a distance specific to the reproducing/recording apparatus. Therefore, the cartridge case having the first and second locking steps corresponding to the contact member and the sensor piece can be identified as a dedicated cartridge case for the recording/reproducing apparatus.

Effects of the invention According to this invention, the compatibility of the cartridge case with the recording/playback device can be reliably identified at the loaded position of the cartridge case, thereby preventing damage to the main body of the recording/playback device and the cartridge case. It is possible to prevent each type of failure and reduce the number of failures.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

Embodiment FIG. 1 is a plan view of a cartridge case equipped with a part of the identification structure of a compatible cartridge case according to an embodiment of the present invention, and FIG. 2 is a plan view of a cartridge case in which the cartridge case shown in FIG. FIG. 3 is an enlarged plan sectional view of the main part showing a state in which the cartridge case is properly loaded into the recording and reproducing apparatus; FIG. .

It should be noted that the following example is only one specific example of this invention, and the technical scope of this invention is not limited by this example.

First, referring to FIG. 1, a cartridge case 1 equipped with a part of the identification structure of a compatible cartridge case according to this invention will be described. The cartridge case 1 houses a disk 7 and is removably loaded into a cartridge case loading section of a recording/reproducing apparatus (not shown). The cartridge case 1 has an opening 8 that exposes the recording/reproducing area of the disk 7 housed in the case on the case surface so that it can come into contact with a write/read head (not shown) of the recording/reproducing device. and a center hole 9 for a disk rotation bearing (not shown) which is brought into contact to drive the disk disk 7, and when the cartridge case 1 is loaded into the cartridge case loading section. A shutter 2 having an opening 2' that opens and closes the opening 8 and the center hole 9 by sliding on the surface of the case is mounted.

Next, as one of the characteristic components of this embodiment, on both side surfaces of the cartridge case 1, a notch step 4 (first engagement step) extending along the side surface and this notch step are provided. Recessed portions 3 (second engaging step portions) located in the intermediate portions of portions 4 are provided symmetrically as viewed in FIG. 1. This is due to the contact and engagement with the contact member and sensor piece, which will be described later.
This is to enable at least one of the cartridges to function when the cartridge case 1 is turned over, so that recording and reproduction of the disk 7 can be performed on both the front and back sides.

In this case, the cutout stepped portion 4 is formed in the cartridge case 1, for example, as shown in FIG.
The center of the recess 3 is set at a distance l ₁ from the distal end of the cartridge case 1 toward the rear end, and the center of the recess 3 is set at a distance l ₂ from the notch step 4 toward the distal end of the cartridge case 1. has been done.

On the other hand, as shown in FIG. 2, when the cartridge case 1 is loaded into the cartridge case loading section of a recording and reproducing apparatus (not shown), the cartridge case 1 comes into contact with the cutout stepped section 4. A contact member 6 is provided, and a sensor piece 5 is provided which engages with the recess 3 when the contact member 6 is in contact with the cutout step 4. The center of the sensor piece 5 is provided at a distance l ₂ from the abutment member 6 so as to face the recess 3 located on the distal end side of the cartridge case 1 from the notch step 4 .

The sensor piece 5 operates a sensor (not shown) connected to the sensor piece 5 by engaging with the recess 3 of the cartridge case 1, and receives a position confirmation signal of the cartridge case 1 from this sensor. It is set up to send out. The position confirmation signal sent from the sensor is transmitted to a control unit (not shown) installed inside the main body of the device, and thereby the recording and reproducing device moves to the next operation such as loading the disk 7. .

Thus, in FIG. 2, when the cartridge case 1 is loaded into the cartridge case loading section (not shown), at a distance _l1 , the cartridge case is first loaded into the notch stepped portion 4 formed in the cartridge case 1. The abutting member 6 of the section abuts.

Accordingly, a sensor piece 5 equipped on the cartridge case loading section at a distance l ₂
is formed in the cartridge case 1.
A position confirmation signal of the cartridge case 1 sent from a sensor connected to the sensor piece 5 is sent to a predetermined control section as appropriate.

At this time, the distance l ₂ between the abutment member 6 of the cartridge case loading section and the center of the sensor piece 5 is set as a characteristic specific to the recording/reproducing device, and a notch provided at the same distance l ₂ is set. The cartridge case 1 having the stepped portion 4 and the recessed portion 3 is identified by the control section as a dedicated cartridge case for the recording/reproducing apparatus. In this case, for example, the cartridge case 1 is maintained in the cartridge case loading section and is not removed from the recording/reproducing apparatus.

Next, in Fig. 3, a case will be described in which an incompatible cartridge case 1' is loaded into the recording/reproducing device described in Figs. 1 and 2. The cartridge case 1' prepared here is as follows:
The notched step 4' is provided at a distance l3 which is shorter by a length d from the tip of the cartridge case 1' as compared with the notched step 4 provided in the cartridge case ₁ shown in FIG.

Therefore, when the cartridge case 1' is loaded into the cartridge case loading section of the recording/reproducing apparatus, the abutting member 6 of the cartridge case loading section is at a distance d from the notch stepped portion 4' of the cartridge case 1'. Therefore, the sensor piece 5 stops at a position separated from the recess 3 by this distance d, and cannot engage with the recess 3.

Therefore, the sensor piece 5 cannot operate the sensor, and the cartridge case 1' is loaded into the cartridge case loading section without the case position confirmation signal being sent from the sensor, and the control (not shown) is caused. The department determines that this cartridge case 1' is not compatible with the recording/reproducing apparatus, and, for example, issues an order to a predetermined related mechanism to remove such an incompatible cartridge case 1' from the apparatus main body. emits.

In the above configuration, if the compatibility or non-compatibility between the cartridge case loading section and the cartridge case can be identified, for example, in the case of an incompatible cartridge case, even if the cartridge case is being loaded, Since the cartridge case can be removed from the cartridge case loading section, there is also the advantage that damage or deformation inside the recording/reproducing apparatus can be avoided at an early stage.
